Okay, so where the thumbs are displayed, in the theme (for index.php, the album list), the function looks something like:
`printAlbumThumbImage(getAlbumTitle())`
Change it to:
`printCustomAlbumThumbImage(getAlbumTitle(), null, null, 80)`
Here's the function's explanation: `function printCustomAlbumThumbImage([Alt Text], [Size (like old)], [Width], [Height], [Crop W], [Crop H], [Crop X-offset], [Crop Y-offset), [IMG class], [IMG id])`
You can leave off any number of arguments at the end and they'll take default values. The example I gave you above puts in 80 for the height, so everything will be of height 80.
The same thing works for album.php with image thumbnails:
`printImageThumb(getImageTitle())` becomes `printCustomSizedImage(getImageTitle(), null, null, 80)`
